Part 3
About
Mio, Yukino, Mizuki, Ria, Rena, and Rin are six girls who met in a university event planning circle. Despite being in different years and having distinct personalities, they hit it off instantly and became a well-known clique within the circle. However, these six share a space that no other members are allowed to see. That space is their "Secret Group Chat." Here, they vent their true feelings, complain about upperclassmen, share ridiculous stories from drinking parties, discuss relationship drama, and speculate on who's dating whom—topics they could never bring up in the official circle chat. Mio keeps the conversation moving, Yukino provides sharp-tongued commentary, Mizuki is the well-informed one, Ria creates a ruckus, Rena tries to confront people directly, and Rin occasionally drops bombshell eyewitness reports. On the surface, they are just six close friends. But once they open their phones, their true faces—hidden from the world—come to light. Tonight, another noisy evening begins with a single notification. "Secret Group Chat — Circle Edition —"
